Is the psii the source of electrons

WitrynaIn the photosystem II (PSII) reaction center, energy from sunlight is used to extract electrons from water. The electrons travel through the chloroplast electron transport chain to photosystem I (PSI), which reduces NADP + to NADPH. The electron transport chain moves protons across the thylakoid membrane into the lumen. WitrynaIt is asked whether there is a plant which can bypass the PSII for doing photosynthesis. I think there should be a source for electron generation and excitation, in the plant the electrons...
